A new class of thermoplastic elastomers has been created by introducing nanoscale‐dispersed lignin (a biomass‐derived phenolic oligomer) into nitrile rubber. Temperature‐induced controlled miscibility between the and rubber during high shear melt‐phase synthesis allows tuning material's morphology performance. The sustainable product unprecedented yield stress (15–45 MPa), strain hardens at large deformation, outstanding recyclability. multiphase polymers developed from an equal‐mass mixture...
Abstract Extracellular vesicles (EVs) are emerging as a promising drug delivery vehicle they biocompatible and capable of targeted delivery. However, clinical translation EVs remains challenging due to the lack standardized scalable manufacturing protocols consistently isolate small (sEVs) with both high yield purity. The heterogenous nature sEVs leading unknown composition biocargos causes further pushback safety concerns. In order address these issues, we developed robust...
Electric double-layer capacitors (EDLCs), or supercapacitors, rely on rapid electrosorption of ions into porous carbon electrodes to achieve high power densities and long lifetimes. Ionic liquid (IL) electrolytes offer large operating voltage windows can potentially increase the energy density EDLCs if electrode/electrolyte interface is properly optimized. Herein, we present molecular level measurements ion dynamics 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIm-TFSI) IL...
High-performance multiphase thermoplastics were synthesized by reactive mixing of unmodified industrial lignin and low-cost additives in a matrix general-purpose acrylonitrile-butadiene rubber (NBR).
Aims: The authors investigated whether displaying more than one homing peptide enhanced the tumor-targeting efficiency of exosomes. Materials & methods: Exosomes from human embryonic kidney cells (HEK293F) were engineered to display either mono- or dual-tumor-penetrating peptides, iRGD and tLyp1. purified via tangential flow filtration followed by ultracentrifugation. Results: When loaded with doxorubicin (Dox), dual iRGD-tLyp1 exosomes strongly Dox uptake in both MCF-7 MDA-MB-231 breast...
In this effort, we report the compatibilization of biomass-derived lignin polymer in acrylonitrile butadiene styrene (ABS) thermoplastic matrix without loss mechanical properties via poly(ethylene oxide) (PEO)-mediated macromolecular self-assembly. ABS was blended with different concentrations, and blends 10 wt % PEO (relative to lignin) were prepared. The relative tensile strength improved slightly at low content but diminished rapidly as increased. However, inclusion an interfacial...
A facile route to fabrication of porous high surface area nanofibers is demonstrated via electrospinning a polymer blend followed by selective removal one the components. First, electrospinnability Nafion–polyacrylonitrile (PAN) solutions in N,N-dimethylformamide studied over wide range compositions. Pure Nafion are not electrospinnable themselves owing presence aggregates solution due ionic interactions, thereby resulting low viscosities. Addition only 5 wt% PAN allows us successfully...
Abstract A simple, green approach to fabricating porous free‐standing carbon films is presented. An alkaline solution of low‐cost, renewable lignin and graphene oxide (GO) cast, followed by simultaneous carbonization activation. Lignin, which the least valued product from several biomass processing industries, an efficient source when used as intercalating agent separate sheets derived homogeneous GO/lignin nanocomposite prepared aqueous (KOH) solution. After thermal treatment show complete...
Abstract A straightforward but effective approach to fabricate shape‐memory polyurethane thermosets by tailoring the soft phase composition of two‐ and four‐armed polycaprolactone (PCL) polyols is described. As crystallization PCL has an effect on driving self‐assembly H‐bonds, a good balance tensile performance thermo‐healability can be achieved regulating ratio between PCL‐diol PCL‐tetrol in phase. The inferior ability segments near branching point gives rise enhancement both overall...

PBI exhibited high sensitivity rapid optical response CN due to intramolecular charge transfer (ICT) mechanism. The limit of 1.15×10 −7 M in mixture DMSO/H 2 O (1 : 1, v/v). Moreover, probe demonstrated selectivity over other common anions,...

Abstract The miscibility of poly(vinyl chloride) (PVC) with various ethylene copolymers and terpolymers were investigated using FT‐IR spectroscopy. All blends reported 50/50 by weight. In PVC ethylene/dimethyl acrylamide copolymer (E/DMA), frequency shifts observed in the amide carbonyl (proton acceptor) α‐hydrogen donor) characteristic bands. ethylene/ethyl acrylate/carbon monoxide terpolymer (E/EA/CO), both ester ketone frequencies showed mutual appeared as if they merged together. Small...
